TRIMMING ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 334,114, dated January 12, 1886.

Application filed October 8, 1885. Serial No. 179,325.

To all whom it may concern:

Be it known that I, JAMES WILLIAM EAST- WOOD, residing at Thorold, in the county of WVelland, in the Province of Ontario, Canada, have invented new and useful Improvements in Trimming Attachments for Sewing Machines, (for which I have obtained a patent in Canada, No. 22,276, bearing date August 21, 1885,) of which the following is a specification.

My invention relates to attachments for sewing-machines by means of which felt and leather goods and other articles may be sewed and trimmed in one operation.

The object of my invention is to attach a reciprocating cutter or knife to the needle-bar, which will operate simultaneously with the needle-bar and out the work at a given distance from the needle or stitch. I attain this object by detachably securing to the needlebar a block or head, which will carry detachably both the needle and knife or cutter, which latter may be either straight or bent, according to the distance the cut is desired from the stitch.

Figure 1 is a front elevation of the needlebar with the head and knife placed in position, and showing throat-plate in section. Fig. 2 is a horizontal or cross section on line 00 as. Fig. 3 is a side elevation.

A is the reciprocating needle-bar of a sewing-machine. having a longitudinal groove, a, cut in it to receive t h e i ip gdle B.

G is 60k or head adapted to fit the end of the needle-bar, to which it is heldby setscrew D, passing from the front or back. An other set-screw, B, on the needle side of the head, clamps the needle in the head and needle-bar. Directly opposite the needle a wide shallow groove or recess is cut to form a bed for the cutter or knife F, which is clamped in (No model.) Patented in Canada August 21, 1885, No. 22,276.

place by a set-screw, G, passing through-a slot, f, in the knife. The knife or cutter F consists of a narrow plate or strip of steel sharpened at the lower end to form the cutting edge. The cutting edge is preferably slightly rounded. By means of the slot f the cutter may be adjusted vertically and its wear taken up. The cutter or knife may either be bent, as shown in the drawings, Fig. 1, or it may be straight, according to whether the cutter is desired to be nearer to or farther from the stitch. When bent, it may be so more or less, and it may be bent toward or from the needle. To prevent the sharp cutting-edge of the knife coming in contact with the hard metal face of the throat-plate, I out out the portion I of the plate which would be touched by the knife, and the slot in the plate so formed may be left open or it may be filled with lead or any other soft metal or leather, which will not blunt the cutting-edge by contact with the knife.

It will be observed that the knife operates vertically simultaneously with the needle, the cutting operation being performed when the needle descends; but either needle 'or knife may be used independently of each other, if desired.

I claim as my invention- In combination with the needle-bar of a sewing-machine, needle-bar A, needle B, screw B, head 0, set-screw D, knife F, having slot f, set-screw G, and throat-plate H, provided with slot I, all substantially as set forth.

Signed at Thorold, Ontario, Canada, this 30th day of September, 1885.

JAMES WILLIAM EASTWOOD.
